Question

Comets that visit the inner Solar System were kicked there from the Kuiper Belt or Oort Cloud by gravitational close encounters with other objects. Pluto travels through the inner edge of the Kuiper Belt. As Ceres is just a large asteroid, could Pluto be just a large Kuiper Belt comet nucleus?

Answer 1

Answer:

There's additional information which helps better answer this question:

Which of the following properties of Pluto would best help answer this question?

A. surface temperature  B. composition  C. apparent brightness    

   D. color E. orbital period

Pluto is kind of a mixture of Rock and water ice, with a 70% rock and the rest water ice, estimated that the 70% rock part is its core and the other 30% would be its mantle consisting of water ice and other gases such as nitrogen, carbon monoxide and methane; it is part of the Kuiper belt and it's considered a dwarf planet due it orbits the Sun  and it's bigger than other asteroids and comets to be a dwarf, but not big enough to be a regular planet. Comets are generally more fragile than big asteroids and dwarf planets such as Pluto, their composition make them different objects due cometary nuclei is more like a blend of dust, some roks, water ice and some other gases, they're maily icy dirt balls.

Thus is mostly Pluto's composition which differ it from comets, therefore the best option would be:  B.Composition
